Abstract

The device has two electrical machines (6, 7) and their respective shafts (8, 9). A mechanical assembly connects a shaft (2) of an engine, the shafts (8, 9), and a shaft (4) of the wheels (5) with each other. The shaft (2) and the shafts (8, 9) are connected to a shaft (55) of a mechanical oil pump through two free wheels mechanisms (12), where the mechanisms have two distinct, identical and independent free wheel apparatus (56, 57). The apparatus (56, 57) have their respective rings driving the driven rings, where the rings turn in the same rotational axis of the shaft (55).

Description

Dispositif de transmission de puissance d'un véhicule automobile muni d'unPower transmission device of a motor vehicle equipped with a

mécanisme à roues libres entraînant une pompe à huile La présente invention concerne un dispositif de transmission de puissance d'un véhicule automobile muni d'un mécanisme à roues libres entraînant une pompe à huile. L'invention a notamment pour but de limiter au maximum des frottements entre des pièces mécaniques du dispositif de transmission. L'invention trouve une application particulièrement avantageuse dans le domaine des véhicules automobiles à motorisation hybride, mais elle pourrait aussi être utilisée avec d'autres types de véhicules terrestres à motorisation hybride.  The present invention relates to a power transmission device of a motor vehicle provided with a freewheel mechanism driving an oil pump. The invention particularly aims to minimize friction between mechanical parts of the transmission device. The invention finds a particularly advantageous application in the field of hybrid motor vehicles, but it could also be used with other types of hybrid-powered land vehicles.

On connaît des dispositifs de transmission pour véhicules hybrides qui comportent un moteur thermique, deux machines électriques, et un, deux, ou plusieurs trains épicycloïdaux reliés entre eux à l'intérieur d'un ensemble mécanique. Un exemple d'un tel dispositif est décrit dans la demande de brevet français FR-A-2832357. Avec ces dispositifs de transmission, la puissance du moteur thermique peut être soit transmise directement aux roues, soit dérivée en passant par une chaîne électrique. La chaîne électrique comporte les machines électriques susceptibles de se comporter en moteur ou en générateur selon des valeurs d'énergies reçues électriquement et ou mécaniquement respectivement sur leurs bornes et leur arbre. La puissance dérivée est retransmise aux roues du véhicule ou stockée le cas échéant dans un système de stockage. Cette puissance dérivée permet d'adapter précisément le couple appliqué aux roues du véhicule à celui demandé par un conducteur, tout en adaptant également précisément les couple et régime du moteur thermique de façon à optimiser son rendement. Cette adaptation du couple appliqué aux roues procure un meilleur confort de conduite, tandis que l'adaptation du point de fonctionnement du moteur thermique permet une économie d'énergie.  Transmission devices for hybrid vehicles are known which comprise a heat engine, two electrical machines, and one, two or more epicyclic gear trains connected to each other within a mechanical assembly. An example of such a device is described in French patent application FR-A-2832357. With these transmission devices, the power of the engine can be either transmitted directly to the wheels, or derived through an electrical chain. The electrical chain comprises electric machines that can behave as a motor or generator according to energy values received electrically and / or mechanically respectively on their terminals and their shaft. The derived power is retransmitted to the wheels of the vehicle or stored where appropriate in a storage system. This derived power makes it possible to precisely adapt the torque applied to the wheels of the vehicle to that requested by a driver, while also precisely adapting the torque and speed of the engine so as to optimize its efficiency. This adaptation of the torque applied to the wheels provides better driving comfort, while the adaptation of the operating point of the heat engine allows energy savings.

Lorsqu'un système de stockage, tel qu'une batterie, lui est relié, un tel dispositif est susceptible de fonctionner dans deux modes de fonctionnement. En effet, dans un premier mode de fonctionnement appelé mode hybride, l'arbre de roues est entraîné à la fois par le moteur thermique et par au moins une des machines électriques. Dans un deuxième mode appelé mode électrique, l'arbre de roues est entraîné par au moins une des machines électriques tandis que le moteur thermique est éteint.  When a storage system, such as a battery, is connected to it, such a device is capable of operating in two modes of operation. Indeed, in a first mode of operation called hybrid mode, the wheel shaft is driven both by the engine and by at least one of the electrical machines. In a second mode called electrical mode, the wheel shaft is driven by at least one of the electrical machines while the engine is off.

Pour préserver de l'usure et du grippage des pièces mécaniques de ce dispositif, tels que des pignons, des roulements et des arbres reliés entre eux à l'intérieur de l'ensemble mécanique, on recouvre ces pièces d'une légère couche d'huile. L'ensemble mécanique est ainsi généralement lubrifié dès que l'un des arbres du dispositif entre en rotation. Cette lubrification est généralement réalisée à l'aide d'une pompe à huile mécanique.  To preserve wear and seizure of mechanical parts of this device, such as pinions, bearings and shafts interconnected within the mechanical assembly, these parts are covered with a light coating of oil. The mechanical assembly is thus generally lubricated as soon as one of the shafts of the device rotates. This lubrication is usually performed using a mechanical oil pump.

Cette pompe à huile doit assurer la lubrification des pièces mécaniques, quel que soit le mode de fonctionnement du véhicule: mode hybride ou mode électrique, mais aussi lorsque le véhicule est à l'arrêt, roule en marche arrière ou est remorqué. Autrement dit, quel que soit l'état du véhicule, la pompe à huile doit toujours être entraînée.  This oil pump must lubricate the mechanical parts, whatever the mode of operation of the vehicle: hybrid mode or electric mode, but also when the vehicle is stopped, rolls in reverse or is towed. In other words, whatever the condition of the vehicle, the oil pump must always be driven.

A cet effet, dans les systèmes connus, la pompe à huile est reliée à la fois à l'arbre du moteur thermique et à l'arbre d'une des machines électriques. Cette liaison entre la pompe et les deux arbres est généralement réalisée par l'intermédiaire d'un mécanisme à deux roues libres. Ce mécanisme comporte un anneau entraîné et deux anneaux entraînants. Les anneaux entraînants entraînent l'anneau entraîné lorsqu'ils tournent à une vitesse supérieure à celle de l'anneau entraîné. L'anneau entraîné est susceptible de tourner librement lorsque les anneaux entraînants tournent à une vitesse inférieure à celle de l'anneau entraîné.  For this purpose, in known systems, the oil pump is connected both to the shaft of the engine and to the shaft of one of the electric machines. This connection between the pump and the two shafts is generally carried out by means of a mechanism with two free wheels. This mechanism comprises a driven ring and two driving rings. The driving rings drive the driven ring when they rotate at a higher speed than the driven ring. The driven ring is rotatable freely when the driving rings rotate at a lower speed than the driven ring.

Plus précisément, dans les systèmes connus, un arbre de la pompe est relié à l'anneau entraîné, tandis que l'arbre du moteur et l'arbre de la machine électrique sont reliés chacun à un anneau entraînant. Ainsi, la pompe peut être entraînée à la vitesse de rotation la plus élevée des deux arbres, afin d'assurer une lubrification sur les points de fonctionnement les plus sollicitant.  More specifically, in known systems, a shaft of the pump is connected to the driven ring, while the motor shaft and the shaft of the electric machine are each connected to a driving ring. Thus, the pump can be driven at the highest rotational speed of the two shafts to provide lubrication at the most demanding operating points.

Toutefois, ce type de système ne possède pas un fonctionnement aussi robuste que souhaité. En effet, dans un tel système, le dysfonctionnement d'un des éléments entraîne généralement le dysfonctionnement global du système. Par exemple, si l'anneau entraîné est endommagé, aucune des deux roues ne peut entraîner en rotation l'arbre de la pompe.  However, this type of system does not have as robust a functioning as desired. Indeed, in such a system, the malfunction of one of the elements generally causes the overall malfunction of the system. For example, if the driven ring is damaged, neither of the two wheels can rotate the pump shaft.

En outre, la fabrication industrielle d'un tel système peut s'avérer difficile et chère. En effet, une telle pièce est complexe dans sa structure et nécessite donc de nombreuses opérations d'usinage. Or chaque opération prend du temps et fait augmenter le prix de revient du système.  In addition, the industrial manufacture of such a system can be difficult and expensive. Indeed, such a part is complex in its structure and therefore requires many machining operations. But each operation takes time and increases the cost of the system.

L'invention se propose de résoudre ces problèmes de 5 dysfonctionnement et de coût.  The invention proposes to solve these problems of malfunction and cost.

A cet effet, dans l'invention, le mécanisme à deux roues libres est réalisé à partir de deux appareils roues libres à cages séparées et distinctes. Autrement dit, ces appareils roue libre possèdent des anneaux entraînés distincts et indépendants. Ainsi, dans le cas où l'anneau entraîné d'un des appareils est endommagé, à la suite d'un choc par exemple, le deuxième appareil peut toujours fonctionner correctement, indépendamment de l'appareil endommagé.  For this purpose, in the invention, the two-wheel free mechanism is made from two separate and separate cage freewheel devices. In other words, these freewheel devices have distinct and independent driven rings. Thus, in the case where the driven ring of one of the devices is damaged, following an impact for example, the second device can still function properly, regardless of the damaged device.

En outre, dans l'invention, la fabrication industrielle du mécanisme peut être réalisée à bas coût, puisqu'il peut être réalisé à partir de deux appareils roue libre identiques. Or chaque appareil est facile à réaliser indépendamment puisqu'il comporte uniquement un anneau entraînant et un anneau entraîné. Pour fabriquer l'invention, on fabrique donc en grande quantité des appareils élémentaires simples, alors que pour fabriquer le système de l'état de la technique, il était nécessaire de fabriquer des mécanismes complexes en petite quantité.  In addition, in the invention, the industrial manufacture of the mechanism can be achieved at low cost, since it can be made from two identical freewheel devices. However, each device is easy to perform independently since it comprises only a driving ring and a driven ring. In order to manufacture the invention, simple unitary devices are therefore produced in large quantities, whereas in order to manufacture the system of the state of the art it was necessary to manufacture complex mechanisms in small quantities.

Plus précisément, dans le mécanisme selon l'invention, l'arbre du moteur et l'arbre d'une machine électrique sont reliés chacun à un anneau entraînant. Tandis que l'arbre de la pompe est relié aux deux anneaux entraînés du mécanisme.  More specifically, in the mechanism according to the invention, the motor shaft and the shaft of an electric machine are each connected to a driving ring. While the pump shaft is connected to the two driven rings of the mechanism.

Dans une réalisation particulière, l'arbre de la pompe est relié à l'intérieur des appareils roues libres, tandis que l'arbre du moteur et l'arbre de la machine sont reliés à l'extérieur des appareils roues libres. En variante, les roues libres sont situées l'une au-dessus de l'autre et l'arbre de la pompe est connecté entre les roues libres.  In a particular embodiment, the pump shaft is connected to the inside of the freewheel devices, while the motor shaft and the machine shaft are connected to the outside of the freewheel devices. Alternatively, the freewheels are located one above the other and the pump shaft is connected between the freewheels.

Dans une réalisation particulière, les appareils roue libre comportent des galets qui entrent en coopération avec une paroi de l'anneau entraîné. Dans une position arc-boutée, ces galets entraînent en rotation l'anneau entraîné, tandis que dans une position libre, ces galets permettent la libre rotation des anneaux entraînés.  In a particular embodiment, the freewheel devices comprise rollers which cooperate with a wall of the driven ring. In a braced position, these rollers rotate the driven ring, while in a free position, these rollers allow free rotation of the driven rings.

L'invention concerne donc un dispositif de transmission de puissance d'un véhicule automobile muni d'un mécanisme à roues libres entraînant une pompe à huile, ce dispositif étant disposé entre un arbre d'un moteur thermique et un arbre de roues, ce dispositif comportant - au moins une machine électrique comportant un arbre de machine, - un ensemble mécanique reliant entre eux l'arbre du moteur, l'arbre de machine et l'arbre de roues, - la pompe comportant un arbre de pompe, -l'arbre du moteur et l'arbre de machine étant reliés à l'arbre de pompe par l'intermédiaire d'un mécanisme à deux roues libres, caractérisé en ce que: - le mécanisme à deux roues libres comporte deux appareils roue libre distincts et indépendants.  The invention therefore relates to a power transmission device of a motor vehicle provided with a freewheel mechanism driving an oil pump, this device being disposed between a shaft of a heat engine and a wheel shaft, this device comprising - at least one electric machine having a machine shaft, - a mechanical assembly interconnecting the motor shaft, the machine shaft and the wheel shaft, - the pump comprising a pump shaft, motor shaft and machine shaft being connected to the pump shaft via a two-wheel free mechanism, characterized in that: - the two-wheel free mechanism comprises two separate and independent freewheel devices .

Ces figures sont données à titre illustratif mais nullement limitatif de l'invention.

These figures are given for illustrative purposes but in no way limitative of the invention. These figures show: FIG. 1: a schematic representation of a transmission device according to the invention comprising a mechanical pump connected to a motor shaft and to a shaft of one of the electrical machines; - Figure 2: a schematic representation of a transmission device according to the invention comprising a mechanical pump connected inside a mechanical assembly formed of two planetary gear trains; FIGS. 3: schematic representations of connections between a pump shaft, an engine shaft and a machine shaft via a two-wheel free mechanism according to the invention; - Figures 4: schematic representations of a freewheel device according to the invention.

La figure 1 montre une représentation schématique d'un dispositif 1 de transmission entre un arbre 2 d'un moteur 3 thermique et un arbre 4 de roues 5. Ce dispositif 1 comporte une première machine 6 électrique et une deuxième machine 7 électrique comportant respectivement un arbre 8 et un arbre 9. L'arbre 2, l'arbre 4, l'arbre 8 et l'arbre 9 sont reliés entre eux par l'intermédiaire d'un ensemble 10 mécanique. Une pompe 11 à huile mécanique est reliée à un arbre 2 du moteur 3 et à un des arbres 8, 9 par l'intermédiaire d'un mécanisme 12 à deux roues libres. Comme on va le voir, le dispositif 1 est susceptible de fonctionner dans deux états de fonctionnement.  FIG. 1 shows a schematic representation of a transmission device 1 between a shaft 2 of a thermal engine 3 and a wheel shaft 4. This device 1 comprises a first electrical machine 6 and a second electrical machine 7 respectively comprising a 8 and a shaft 9. The shaft 2, the shaft 4, the shaft 8 and the shaft 9 are connected to each other via a mechanical assembly 10. A mechanical oil pump 11 is connected to a shaft 2 of the engine 3 and to one of the shafts 8, 9 via a mechanism 12 with two freewheels. As will be seen, the device 1 is capable of operating in two operating states.

Plus précisément, l'ensemble 10 mécanique comporte plusieurs trains épicycloïdaux reliés entre eux. Chaque train épicycloïdal comporte dans le cas général trois différents éléments mobiles en rotation: un planétaire, un porte-satellites et une couronne qui engrènent mutuellement. Dans l'ensemble 10, les trains épicycloïdaux sont reliés entre eux de manière à présenter deux degrés de libertés et quatre éléments mobiles externes auxquels on va relier l'arbre 2 du moteur 3, l'arbre 4 de roues 5 et les deux arbres 8 et 9 des machines 6 et 7 électriques.  More specifically, the mechanical assembly comprises several epicyclic gear trains connected to each other. Each epicyclic gear train comprises in the general case three different rotating elements: a sun gear, a planet carrier and a crown which mesh with each other. In the assembly 10, the planetary gear trains are connected to each other so as to have two degrees of freedom and four external movable elements to which will be connected the shaft 2 of the motor 3, the shaft 4 of wheels 5 and the two shafts 8 and 9 electric machines 6 and 7.

Ainsi, l'arbre 2 est relié à un premier élément 13 mobile de l'ensemble 10. L'arbre 8 est relié à un deuxième élément 14 mobile de l'ensemble 10. L'arbre 4 est relié à un troisième élément 15 mobile de l'ensemble 10. L'arbre 9 est susceptible d'être relié soit au troisième élément 15 mobile en prise directe avec l'arbre 4 de roues 5, soit à un quatrième élément 16 mobile de l'ensemble 10. Cette liaison de l'arbre 9 au troisième élément 15 ou au quatrième élément 16 mobile est réalisée notamment par l'intermédiaire d'un crabot 17 et d'un premier et deuxième pignon 18 et 19.  Thus, the shaft 2 is connected to a first movable element 13 of the assembly 10. The shaft 8 is connected to a second mobile element 14 of the assembly 10. The shaft 4 is connected to a third movable element 15 10. The shaft 9 can be connected either to the third movable element 15 in direct contact with the wheel shaft 4 or to a fourth movable element 16 of the assembly 10. This connection the shaft 9 to the third element 15 or the fourth movable element 16 is made in particular by means of a dog 17 and a first and second pinion 18 and 19.

Par ailleurs, une chaîne 20 électrique relie la première et la deuxième machine 6 et 7 entre elles. Cette chaîne 20 comporte notamment un premier onduleur 21, un deuxième onduleur 22, ainsi qu'un bus 23 électrique comportant deux connexions 24 et 25. Dans la pratique, ce bus électrique 23 est un bus à tension continue. Des phases 26-28 de la première machine 6 sont reliées au premier onduleur 21 qui est lui-même relié aux deux connexions 24 et 25 par intermédiaire de deux liaisons filaires 29 et 30. Des phases 31-33 de la deuxième machine 7 sont reliées au deuxième onduleur 22 qui est lui-même relié aux deux connexions 24 et 25 par l'intermédiaire de deux liaisons filaires 34 et 35.  Furthermore, an electrical chain connects the first and the second machine 6 and 7 to each other. This chain 20 includes in particular a first inverter 21, a second inverter 22, and an electric bus 23 having two connections 24 and 25. In practice, this electric bus 23 is a DC bus. Phases 26-28 of the first machine 6 are connected to the first inverter 21 which is itself connected to the two connections 24 and 25 via two wire links 29 and 30. Phases 31-33 of the second machine 7 are connected. to the second inverter 22 which is itself connected to the two connections 24 and 25 via two wire links 34 and 35.

En mode hybride ou en mode tout électrique, les machines 6 et 7 peuvent se comporter soit en moteur, soit en générateur. Lorsqu'une des machines 6 ou 7 se comporte en générateur, les signaux de tension alternatifs observables entre les phases 26-28 ou 31-33 sont transformés en un signal de tension continue observable sur le bus 23, par l'onduleur 21 ou 22 associé à cette machine. Lorsqu'une des machines 6 ou 7 se comporte en moteur, le signal de tension continue observable sur le bus 23 est transformé en signaux de tension alternatifs et déphasés par l'onduleur 21 ou 22 associé à cette machine. Ces signaux de tension sont appliqués sur les phases de la machine 6 ou 7 qui fonctionne en moteur.  In hybrid mode or all-electric mode, the machines 6 and 7 can behave either as a motor or as a generator. When one of the machines 6 or 7 behaves as a generator, the AC voltage signals observable between the phases 26-28 or 31-33 are transformed into a DC voltage signal observable on the bus 23, by the inverter 21 or 22 associated with this machine. When one of the machines 6 or 7 behaves as a motor, the DC voltage signal observable on the bus 23 is converted into alternating voltage signals and out of phase by the inverter 21 or 22 associated with this machine. These voltage signals are applied to the phases of the machine 6 or 7 which operates as a motor.

Dans le cas où aucun système de stockage n'est relié au bus 23, l'énergie produite par une des machines est automatiquement consommée par l'autre machine. En variante, un système de stockage, tel qu'une batterie 36, est relié au bus 23. Dans une phase de récupération particulière, les deux machines 6 et 7 peuvent fonctionner simultanément ou l'une après l'autre en générateur, de manière à stocker le plus d'énergie possible dans la batterie 36. Dans une phase d'accélération particulière, les deux machines 6 et 7 peuvent fonctionner simultanément en moteur, par exemple pendant que le moteur 2 est éteint.  In the case where no storage system is connected to the bus 23, the energy produced by one of the machines is automatically consumed by the other machine. Alternatively, a storage system, such as a battery 36, is connected to the bus 23. In a particular recovery phase, the two machines 6 and 7 can operate simultaneously or one after another as a generator, so that to store as much energy as possible in the battery 36. In a particular acceleration phase, the two machines 6 and 7 can operate simultaneously as a motor, for example while the engine 2 is off.

Dans une réalisation particulière, la pompe 11 est reliée à l'arbre 2 du moteur 3 et à l'arbre 8 de la première machine 6 par l'intermédiaire du mécanisme 12 à deux roues libres. Cette pompe 11 a pour but de lubrifier des éléments mécaniques de l'ensemble 10 mécanique, ainsi que les arbres 2, 4, 8 et 9. Cette pompe 11 est activée dès qu'un des arbres 2, 4, 8 et 9 entre en rotation. En variante, la pompe 11 est reliée à l'arbre 2 du moteur 3 et à l'arbre 9 de la machine 7. Dans une autre variante, la pompe 11 est reliée simultanément à l'arbre 2, à l'arbre 8 et à l'arbre 9 par l'intermédiaire d'un mécanisme 12 à trois roues libres.  In a particular embodiment, the pump 11 is connected to the shaft 2 of the motor 3 and to the shaft 8 of the first machine 6 via the mechanism 12 with two freewheels. This pump 11 is intended to lubricate the mechanical elements of the mechanical assembly, as well as the shafts 2, 4, 8 and 9. This pump 11 is activated as soon as one of the shafts 2, 4, 8 and 9 comes into operation. rotation. In a variant, the pump 11 is connected to the shaft 2 of the motor 3 and to the shaft 9 of the machine 7. In another variant, the pump 11 is connected simultaneously to the shaft 2, to the shaft 8 and to the shaft 9 via a mechanism 12 with three freewheels.

La figure 2 montre une représentation schématique d'un dispositif 1 de transmission selon l'invention comportant un ensemble 10 mécanique formé par un premier train 41 épicycloïdal et d'un deuxième train 42 épicycloïdal. La pompe 11 est reliée dans cette réalisation à l'arbre 2 du moteur 3 et à l'arbre 8 de la première machine 6. Pour des raisons de simplicité, la chaîne électrique 20 n'est pas représentée.  Figure 2 shows a schematic representation of a transmission device 1 according to the invention comprising a mechanical assembly 10 formed by a first epicyclic gear 41 and a second epicyclic gear 42. The pump 11 is connected in this embodiment to the shaft 2 of the motor 3 and the shaft 8 of the first machine 6. For reasons of simplicity, the electrical chain 20 is not shown.

Plus précisément, un planétaire 43 du premier train 41 est relié à une couronne 44 deuxième train 42. Et un porte-satellites 45 du premier train 41 portant les satellites 46 et 47 est relié à un porte-satellites 48 du deuxième train portant les satellites 49 et 50. En liant les deux trains 41 et 42 par deux liaisons, on limite les quatre degrés de liberté potentiels de l'ensemble 10 à deux et on dispose de quatre éléments mobiles accessibles.  More precisely, a sun gear 43 of the first gear 41 is connected to a second gear crown 44 and a planet carrier 45 of the first gear 41 carrying the satellites 46 and 47 is connected to a planet carrier 48 of the second gear carrying the satellites. 49 and 50. By linking the two trains 41 and 42 by two links, the four potential degrees of freedom of the set 10 are limited to two and there are four accessible moving elements.

Par ailleurs, l'arbre 2 du moteur 3 est relié au planétaire 43 du premier train 41. L'arbre 4 de roues 5 est relié au porte-satellites 48 du deuxième train 42. L'arbre 8 de la première machine 6 est relié à une couronne 51 du premier train 41.  Furthermore, the shaft 2 of the motor 3 is connected to the sun gear 43 of the first gear 41. The wheel shaft 4 is connected to the planet carrier 48 of the second gear 42. The shaft 8 of the first machine 6 is connected. to a ring 51 of the first train 41.

Le crabot 17, en se déplaçant le long de l'arbre 9 de la deuxième machine 7 est susceptible de relier cet arbre 9 soit à un planétaire 52 du deuxième train 42, soit à l'arbre 4 de roues 5. Lorsqu'il se trouve dans une première position P1, le crabot 17 relie l'arbre 9 à l'arbre 4 par l'intermédiaire du pignon 18 et d'une roue 53. Le pignon 19 est alors monté fou sur l'arbre 9. Lorsqu'il se trouve dans une position P2, le crabot 17 relie l'arbre 9 au planétaire 52 par l'intermédiaire du pignon 19 et d'une roue 54. Le pignon 17 est alors monté fou sur l'arbre 9.  The clutch 17, moving along the shaft 9 of the second machine 7 is capable of connecting the shaft 9 to either a sun gear 52 of the second gear 42, or to the shaft 4 of wheels 5. When located in a first position P1, the clutch 17 connects the shaft 9 to the shaft 4 via the pinion 18 and a wheel 53. The pinion 19 is then mounted crazy on the shaft 9. When is in a P2 position, the clutch 17 connects the shaft 9 to the sun gear 52 via the pinion 19 and a wheel 54. The pinion 17 is then mounted loosely on the shaft 9.

En outre, un arbre 55 de pompe est relié à l'arbre 2 du moteur 3 et à l'arbre 8 du moteur 6 par l'intermédiaire du mécanisme 12 à deux roues libres. Ce mécanisme 12 à deux roues libres comporte un premier appareil 56 roue libre et un deuxième appareil 57 roue libre distincts et indépendants. Autrement dit, lorsqu'ils ne sont pas montés à l'intérieur du dispositif 1, ces deux appareils 56 et 57 ne sont pas reliés entre eux.  In addition, a pump shaft 55 is connected to the shaft 2 of the motor 3 and to the shaft 8 of the motor 6 via the mechanism 12 with two freewheels. This mechanism 12 with two freewheels comprises a first device 56 freewheel and a second device 57 freewheel separate and independent. In other words, when they are not mounted inside the device 1, these two devices 56 and 57 are not interconnected.

Dans cette réalisation, l'arbre 2 du moteur 3 est relié au premier appareil 56 par l'intermédiaire d'une roue dentée 58. Et l'arbre 8 de la première machine 6 est relié au deuxième appareil 57 roue libre par l'intermédiaire d'une roue dentée 59. Une description plus détaillée du mécanisme 12 est donnée dans les figures suivantes.  In this embodiment, the shaft 2 of the motor 3 is connected to the first device 56 by means of a toothed wheel 58. And the shaft 8 of the first machine 6 is connected to the second device 57 freewheel via of a toothed wheel 59. A more detailed description of the mechanism 12 is given in the following figures.

Les figures 3 montrent des représentations schématiques de liaisons entre un arbre 55 de pompe, un arbre 2 du moteur et un arbre 60 de machine par l'intermédiaire du mécanisme 12 à deux roues libres selon l'invention. L'arbre 60 de machine est indifféremment l'arbre 8 de la première machine 6 ou l'arbre 9 de la deuxième machine 7.  Figures 3 show schematic representations of connections between a pump shaft 55, a shaft 2 of the motor and a machine shaft 60 through the mechanism 12 with two freewheels according to the invention. The machine shaft 60 is indifferently the shaft 8 of the first machine 6 or the shaft 9 of the second machine 7.

Dans la figure 3a, comme sur la figure précédente, le mécanisme 12 à deux roues libres comporte le premier appareil 56 roue libre et le deuxième appareil 57 roue libre.  In FIG. 3a, as in the previous figure, the mechanism 12 with two freewheels comprises the first freewheel device 56 and the second freewheel device 57.

Le premier appareil 56 roue libre comporte un premier anneau 61 entraînant et un premier anneau 62 entraîné. Le deuxième appareil 57 roue libre comporte un deuxième anneau 63 entraînant et un deuxième anneau 64 entraîné. Ces quatre anneaux 61-64 sont généralement concentriques et sont susceptibles de tourner dans un même sens 65 de rotation autour d'un axe 66. Cet axe 66 est l'axe de l'arbre 55 de pompe.  The first free wheel apparatus 56 includes a first ring 61 driving and a first ring 62 driven. The second freewheel device 57 comprises a second ring 63 driving and a second ring 64 driven. These four rings 61-64 are generally concentric and are able to rotate in the same direction 65 of rotation about an axis 66. This axis 66 is the axis of the pump shaft 55.

Un anneau 61, 63 entraînant entraîne un anneau 62, 64 entraîné en rotation, lorsqu'il tourne à une vitesse supérieure ou égale à celle de l'anneau 62, 64 entraîné. Un anneau 62, 64 entraîné est susceptible de tourner librement lorsqu'il tourne à une vitesse supérieure à celle d'un anneau 61, 63 entraînant.  A ring 61, 63 driving causes a ring 62, 64 rotated, when rotating at a speed greater than or equal to that of the ring 62, 64 driven. A driven ring 62, 64 is rotatable freely when it rotates at a higher speed than a driving ring 61, 63.

L'arbre 55 de pompe est relié aux anneaux entraînés 62, 64. L'arbre 55 est ainsi solidaire des anneaux 62 et 64 entraînés. L'arbre 2 du moteur 3 et l'arbre 60 de machine sont respectivement reliés aux premier et deuxième anneau 61, 63 entraînant.  The pump shaft 55 is connected to the driven rings 62, 64. The shaft 55 is thus integral with the rings 62 and 64 entrained. The shaft 2 of the motor 3 and the machine shaft 60 are respectively connected to the first and second ring 61, 63 driving.

Ainsi, l'arbre 55 de pompe peut toujours être entraîné par l'arbre 2 ou 60 qui tourne le plus vite. En effet, lorsque l'arbre 2 tourne plus vite que l'arbre 60, l'arbre 55 de pompe est entraîné par cet arbre 2, par l'intermédiaire de l'anneau 61 entraînant. En effet, cet anneau 61 entraînant entraîne l'anneau 62 entraîné, pendant que l'anneau 64 entraîné est en roue libre et tourne librement à l'intérieur de l'anneau 63 entraînant.  Thus, the pump shaft 55 can still be driven by the shaft 2 or 60 which rotates the fastest. Indeed, when the shaft 2 rotates faster than the shaft 60, the pump shaft 55 is driven by the shaft 2, through the ring 61 driving. Indeed, this ring 61 driving causes the ring 62 driven, while the ring 64 driven is freewheeling and freely rotates inside the ring 63 driving.

Au contraire, lorsque l'arbre 60 tourne plus vite que l'arbre 2, l'arbre 55 de pompe est entraîné par l'arbre 60 par l'intermédiaire de l'anneau 63 entraînant. En effet, cet anneau 63 entraînant entraîne l'anneau 64 entraîné, pendant que l'anneau 62 entraîné est en roue libre et tourne librement à l'intérieur de l'anneau 61. L'arbre 55 peut ainsi être entraîné même lorsqu'un des arbres 2 ou 60 est à l'arrêt.  On the contrary, when the shaft 60 rotates faster than the shaft 2, the pump shaft 55 is driven by the shaft 60 through the ring 63 driving. Indeed, this ring 63 driving causes the ring 64 driven, while the ring 62 driven is freewheeling and rotates freely inside the ring 61. The shaft 55 can be driven even when a trees 2 or 60 is stopped.

En général, les deux appareils 56 et 57 roue libre utilisés sont identiques. Il est ainsi possible d'utiliser des appareils roue libre standards peu onéreux et facile à fabriquer.  In general, the two devices 56 and 57 freewheel used are identical. It is thus possible to use standard freewheel devices that are inexpensive and easy to manufacture.

Dans cette réalisation, les anneaux 61, 63 entraînants sont des anneaux externes des appareils 56 et 57 roues libres, tandis que les anneaux 62, 64 entraînés sont des anneaux internes. Les anneaux externes possède un diamètre plus grand que les anneaux internes. Comme les appareils sont identiques, les anneaux 61, 63 entraînant, possèdent un même diamètre et les anneaux 62, 64 entraînés possèdent également un même diamètre. En variante, les anneaux 61, 63 sont des anneaux internes, tandis que les anneaux 62, 64 sont des anneaux externes.  In this embodiment, the driving rings 61, 63 are outer rings of the apparatuses 56 and 57 freewheels, while the driven rings 62, 64 are internal rings. The outer rings have a larger diameter than the inner rings. As the devices are identical, the rings 61, 63 driving, have the same diameter and the rings 62, 64 entrained also have the same diameter. Alternatively, the rings 61, 63 are internal rings, while the rings 62, 64 are external rings.

Dans cette réalisation, l'arbre 2 et l'arbre 60 sont reliés directement aux appareils 56 et 57 roues libres. L'arbre 55 de pompe est plein, tandis que l'arbre 2 et l'arbre 60 sont creux. L'arbre 60 de machine possède un diamètre plus grand que celui de l'arbre 2, de manière que l'arbre 2 puisse être monté sur l'arbre 55, à l'intérieur de l'arbre 60. Ces trois arbres 2, 55 et 60 sont coaxiaux, leur trois axes étant confondus avec l'axe 66.  In this embodiment, the shaft 2 and the shaft 60 are connected directly to the apparatuses 56 and 57 freewheels. The pump shaft 55 is solid, while the shaft 2 and the shaft 60 are hollow. The machine shaft 60 has a diameter greater than that of the shaft 2, so that the shaft 2 can be mounted on the shaft 55, inside the shaft 60. These three shafts 2, 55 and 60 are coaxial, their three axes coinciding with the axis 66.

En variante, l'arbre 2 est relié au deuxième appareil 57 roue libre, et entoure l'arbre 60 qui est relié au premier appareil 56 roue libre.  In a variant, the shaft 2 is connected to the second freewheel device 57, and surrounds the shaft 60 which is connected to the first freewheel device 56.

La figure 3b montre une représentation schématique d'une variante du mécanisme 12 à deux roues libres selon l'invention.  FIG. 3b shows a schematic representation of a variant of the mechanism 12 with two freewheels according to the invention.

Dans cette variante, les appareils 56 et 57 roue libre sont concentriques et possèdent des diamètres différents. Par ailleurs, le premier appareil 56 se situe à l'intérieur du deuxième appareil 57.  In this variant, the apparatus 56 and 57 freewheel are concentric and have different diameters. Moreover, the first device 56 is located inside the second device 57.

Plus précisément, l'anneau 61 entraînant et l'anneau 62 entraîné du premier appareil 56 roue libre correspondent respectivement à un anneau interne et à un anneau externe de l'appareil 56. L'anneau 63 entraînant et l'anneau 64 entraîné du deuxième appareil 57 roue libre correspondent respectivement à un anneau externe et à un anneau interne de l'appareil 57.  More precisely, the driving ring 61 and the driven ring 62 of the first freewheel device 56 respectively correspond to an inner ring and to an outer ring of the apparatus 56. The ring 63 driving and the driven ring 64 of the second 57 freewheel apparatus respectively correspond to an outer ring and to an inner ring of the apparatus 57.

Dans chaque appareil, l'anneau externe possède là encore un diamètre plus grand que les anneaux internes.  In each apparatus, the outer ring again has a larger diameter than the inner rings.

L'arbre 55 de pompe est toujours relié aux anneaux 62, 64 entraînés, tandis que les arbres 2 et 60 sont respectivement reliés aux anneaux 61 et 63 entraînants. A cet effet, l'arbre 55 de pompe et l'arbre 60 sont creux, tandis que l'arbre 2 est plein. L'arbre 55 de pompe est ainsi positionné entre l'anneau 62 entraîné du premier appareil 56 et l'anneau 64 entraîné du deuxième appareil 57. Les trois arbres 2, 55 et 60 sont là encore coaxiaux, leur axe se confondant avec l'axe 66.  The pump shaft 55 is always connected to the driven rings 62, 64, while the shafts 2 and 60 are respectively connected to the driving rings 61 and 63. For this purpose, the pump shaft 55 and the shaft 60 are hollow, while the shaft 2 is full. The pump shaft 55 is thus positioned between the driven ring 62 of the first device 56 and the driven ring 64 of the second device 57. The three shafts 2, 55 and 60 are again coaxial, their axis coinciding with the axis 66.

En variante, l'arbre 2 est relié au deuxième appareil 57 roue libre, tandis que l'arbre 60 est relié au premier appareil 56 roue libre.  In a variant, the shaft 2 is connected to the second freewheel device 57 while the shaft 60 is connected to the first freewheel device 56.

Les figures 4 montrent des représentations d'un appareil 70 roue libre selon l'invention. Cet appareil 70 roue libre comporte un anneau 71 interne qui est l'anneau entraînant, et un anneau 72 externe qui est un anneau entraîné. Les deux anneaux 71 et 72 tournent dans un même sens 81 de rotation qui correspond ici au sens trigonométrique. Cet appareil 70 correspond par exemple au premier appareil 62 de la figure 3b.  Figures 4 show representations of a freewheel device according to the invention. This free wheel apparatus has an inner ring 71 which is the driving ring, and an outer ring 72 which is a driven ring. The two rings 71 and 72 rotate in the same direction of rotation 81 which corresponds here to the trigonometric direction. This device 70 corresponds for example to the first device 62 of Figure 3b.

Plus précisément, l'anneau 71 entraînant comporte des galets 73 mobiles disposés sur sa périphérie 78 extérieure. Ces galets 73 sont susceptibles d'entrer en coopération avec une périphérie 74 interne de l'anneau 72 entraîné. Cette périphérie 74 est ici lisse mais en variante, elle pourrait comporter des reliefs.  More specifically, the ring 71 driving includes movable rollers 73 disposed on its outer periphery 78. These rollers 73 are capable of coming into cooperation with an internal periphery 74 of the driven ring 72. This periphery 74 is here smooth but alternatively, it could include reliefs.

Les galets 73 sont orientés dans le sens de rotation des l'anneaux 71 et 72, vers l'extérieur de l'anneau 71 interne. Chaque galet 73 est asymétrique et est susceptible de tourner autour d'un axe 75 de rotation. Cet axe 75 de rotation est excentré par rapport à un centre de gravité d'un galet 73.  The rollers 73 are oriented in the direction of rotation of the rings 71 and 72, towards the outside of the inner ring 71. Each roller 73 is asymmetrical and is rotatable about an axis 75 of rotation. This axis 75 of rotation is eccentric with respect to a center of gravity of a roller 73.

Les galets 73 sont montés sur un ressort 76 circulaire représenté en traits pointillés. Ce ressort 76 assure un passage d'une position arcboutée à une position libre des galets 73.  The rollers 73 are mounted on a circular spring 76 shown in dashed lines. This spring 76 ensures a passage from an arcbouted position to a free position of the rollers 73.

Ainsi, comme le montre la figure 4a, dans la position arc-boutée, le ressort 76 plaque les galets 73 contre la périphérie 74 interne. A cet effet, des forces 77 orientées vers l'extérieur des anneaux 71, 72 sont exercées par le ressort 76 sur les galets 73. Les galets 73 sont plaqués contre la périphérie 74 lorsque l'anneau 71 tourne plus vite que l'anneau 72.  Thus, as shown in Figure 4a, in the abutted position, the spring 76 plates the rollers 73 against the inner periphery 74. For this purpose, forces 77 facing the outside of the rings 71, 72 are exerted by the spring 76 on the rollers 73. The rollers 73 are pressed against the periphery 74 when the ring 71 turns faster than the ring 72 .

Comme le montre la figure 4b, dans la position libre, le ressort 76 plaque les galets 73 contre une périphérie 78 extérieure de l'anneau 71. A cet effet, des forces 79 orientées vers un centre des anneaux 71, 72 sont exercées par le ressort 76 sur les galets 73. Les galets 73 sont plaqués contre la périphérie 78, lorsque l'anneau 72 tourne plus vite que l'anneau 71.  As shown in Figure 4b, in the free position, the spring 76 plates the rollers 73 against an outer periphery 78 of the ring 71. For this purpose, forces 79 oriented towards a center of the rings 71, 72 are exerted by the spring 76 on the rollers 73. The rollers 73 are pressed against the periphery 78, when the ring 72 rotates faster than the ring 71.

En variante, les galets, comme celui référencé 80, sont accrochés sur la périphérie 74 de l'anneau 72. Les galets 80 sont susceptibles de se plaquer contre la périphérie 78 extérieure de l'anneau 71. Dans cette variante, l'anneau 72 externe est l'anneau entraînant, tandis que l'anneau 71 interne est l'anneau entraîné. L'appareil 70 correspond alors aux appareils 56 et 57 de la figure 3a et à l'appareil 57 de la figure 3b.  In a variant, the rollers, like the one referenced 80, are hooked on the periphery 74 of the ring 72. The rollers 80 are capable of pressing against the outer periphery 78 of the ring 71. In this variant, the ring 72 external is the driving ring, while the inner ring 71 is the driven ring. The apparatus 70 then corresponds to the apparatuses 56 and 57 of FIG. 3a and to the apparatus 57 of FIG. 3b.

En variante, l'invention est mise en oeuvre dans des véhicules hybride comportant un moteur et une machine électrique reliés entre eux par l'intermédiaire d'un embrayage.  In a variant, the invention is implemented in hybrid vehicles comprising a motor and an electric machine connected to each other by means of a clutch.

En variante, l'invention est mise en oeuvre avec une pompe à eau du 30 véhicule.  In a variant, the invention is implemented with a water pump of the vehicle.
